| Alexander Graham BellAlexander Graham Bell (3 March
1847 – 2 August
1922) was an eminent scientist,
inventor
and innovator
who is credited with the invention of the telephone.
His father, grandfather and brother had all been associated with work on elocution
and speech,
and both his mother and wife were deaf, profoundly influencing Bell's life's
work.[1]
His research on hearing and speech further led him to experiment with hearing
devices that eventually culminated in Bell being
awarded the first U.S.
patent for the invention of the telephone in 1876.[2]Many other inventions marked Bell's later life including groundbreaking
work in hydrofoils
and aeronautics.
In 1888, Alexander Graham Bell became one of the founding members of the National Geographic Society.[3]
In reflection, Bell
considered his most famous invention an intrusion on his real work as a
scientist and refused to have a telephone in his study.[4]
Upon Bell's death, all telephones throughout the
United States
"stilled their ringing for a silent minute in tribute to the man whose
yearning to communicate made them possible."[5]

Early yearsAlexander Bell
was born in Edinburgh,
Scotland
on March 3,
1847.[6]
Throughout his early life, Bell
was a British subject. The family home was at 16 South Charlotte Street, Edinburgh,
Scotland, and
now has a commemorative marker at the doorstep, marking it as Alexander Graham
Bell's birthplace. He had two brothers: Melville James Bell (1845–1870) and
Edward Charles Bell (1848–1867). Both of his brothers died of tuberculosis,
Edward in 1867 and Melville in 1870.[7]
His father was Professor Alexander Melville Bell, and his mother was
Eliza Grace(nee Symonds).[8]
Although he was born "Alexander", at age ten, he made a plea to his
father to have a middle name like his two brothers.[9]
For his 11th birthday, his father acquiesced and allowed him to adopt the
middle name "Graham" chosen out of admiration for Alexander Graham, a
Canadian being treated by his father and boarder who had become a family
friend.[10]
To close relatives and friends he remained "Aleck" which his father
continued to call him into later life.[11] | |
